GASKET.

Speciicationof Letters Patent. Patented Apr. 26, 1910. Application filedy January 23, 1909. Serial No. 473,886.

To all whom it may concern. y

Beit known that I, WILLIAM A. SCHUL- Trials, a citizen of the United States, and a resident of Cincinnati, county of Hamilton and State of Ohio, have invented a new and 'useful Im rovement in Gaskets, of which tight joints are essential.

In the gaskets heretofore employed in such work at least one of the surfaces presented to the ends of the joint is composed of asbestos, rubber or other suitable packing material, and this, under pressure andthe other necessary conditions of use, adheres to the joint so thatfwhen it becomes necessary, for the purpose of repairs or otherwise to separate the parts, the gasket by reason of such adhesionis destroyed, and anew one mustbe substituted when the parts are reassembled.

Thev object of my invention is to overcome this diliiculty, and to provide a gasket of simple and cheap construction, which may be used over and over again by reason of the suitable protection of the packing material.

Forl the accomplishment of this object my invention consists of a certain novel construction as will hereinafter fully appear.

In the severalgures of the drawings like lnumerals indicate like parts.

In the drawings Figure l is a plan View of my improved gasket. Fig. 2 is a detailed .tails of construction.

view of the same with parts bent back and broken away to show y more clearly the de- 40 Fig. 3 is a cross section. The numeral 1 indicates an annular sheet of thin, pliable metal, preferably copper,

and 2 indicates a similar sheet of the same 45` material, somewhat narrower', however than sheet l.

3 indicates a -layer of asbestos or other suitable packing material, which is placed between the metal sheets l and 2 as clearly 50 shown in Figs. 2 and 3. The sheet l is wide enough so that flanges and 6 may be turned over and made to overlap sheet 2, and the intervening layer of packing, as also shown in Figs.' 2 and 3, and that said sheets l and 2 55 may thus form a metal sheath entirely enveloping said packing layer.

Having thus described my invention what I claim as 'new and desire to secure by Letters Patent, is:

1. A asket comprising a sheet of packing ymateria between two pliable metal sheets',

said metal sheets being joined together at their edges to form a; sheath completel enveloping said sheet of packing materia 2. A asket comprising a sheet of packinfr materia between two annular pliable metal sheets, one of said metal sheets being of greater width than the other, and being turned over at both its outer and inner cir- 70 cumferences-to overlap-said sheet of acking material, and the other of said metal3sheets.
